Does anyone know of some charts or data out there to show avg. power output
for various categories of female riders (elite pro, Pro/1/2, 3, etc.) as a function of the
duration of the testing interval (averages for 5 sec, 1 min, 8 min, 20 min.)

I posted a question a while ago on power output at LT and got some good info back - but
I'm curious if there's data for these other things to guage different abilities (neuromuscular, aerobic, etc.)
